The computer is the data-based electronic machine which was initially invented by Charles Babbage back in 1837. He is called the “Father of computer”. With the discovery of the computer, man has entered a new period of improvement. In this modern era, lives would be impossible without owning a computer. A computer provides us with a wide range of possibilities, and there is an infinite number of things that can be done with the help of a computer.
History of Computer
People have been suffering from complex mathematical calculations for ages. To simplify doing calculations, Wilhelm Schickard invented the first mechanical calculator in 1623. It was not like modern computers. It was only used for addition, subtraction, division, and multiplication. Joseph Marie Jacquard, in 1801, made the first coding language with punched paper cards to instruct his textile loom what pattern to weave.
Around 1890 an engineer known as Herman Hollerith made a computer that could automatically tabulate and add up the data provided. With this development started a new period of advanced computers. Our modern computers are a result of hundreds of modifications done by scientists and engineers over time.
Types of Computers and their hardware
Evolution of computer resulted in its segregation according to peoples’ needs. There are various types of computers like a personal computer, workstation computer, embedded computer and gaming computer. Personal computers, also known as PCs, are the ones that are used for our personal needs.
They are the ones that are found mainly in our homes. A laptop is also a personal computer. Workstation computers are the ones which are used in industries, government institutions, banks, and offices. They usually have features like PowerPoint, spreadsheets, photo editing, and software development.
Embedded computers are used for one thing only. They cannot perform more than one function. For example, the alarm clock is an embedded computer. Gaming computers are the ones that are mainly used for gaming purposes but can also be used as a PC.
The hardware for all kinds of computers is similar. The most important is the CPU. It is the brain of the computer. Next comes the monitor, keyboard, and mouse. The monitor displays the input data, the keyboard helps in typing the data, and the mouse helps in clicking and reaching the icons and documents stored on the computer.
The computer stores memory in the form of data chips. Other hardware includes printers, speakers, and webcams. The speakers are connected to the sound card of the computer system. Computers also have a graphics card for visual effects.
Computers – A Boon or a Bane?
It is a common opinion that computers have made things a lot simpler for humankind. No industry is complete without computers. With the knowledge of computers, literacy of the world is increasing at a rapid rate.
Not only is it easy to exchange information via emails, but trouble-free access to the internet through computers has also led to many discoveries. Employment in the business sectors has also increased. Computers are widely popular in the medical fields for being able to find the cure to many rare diseases.
While there is no doubt that computers are a daily essential, they also have their drawbacks. Using a computer for an extended period regularly can affect the health of the user. Relying on computers too much makes people laid back. There is a considerable increase in the rate of cyber-crime and cyber bullying. Online frauds happen daily.
Conclusion
At the end of the day, whether we use computers to our advantage or disadvantage depends on us. Computers have carved a new path of success for us. Computers connect us with our loved ones from all over the world. There is nothing we cannot achieve if we have a computer by our side.
